Gravity-flow dominated sedimentation on the Buda paleoslope (Hungary): Record of Late Eocene continental escape of the Bakony unit
No full textThe Upper Eocene sequence of the Buda Hills consists of fluvial and shallow marine conglomerates, sandstones, bioclastic shallow-water limestone, marlstone and pelagic Globigerina marl. The succession illustrates rapid, overall subsidence of the area, from terrestrial environments to bathyal depths. Sedimentation occurred on slopes situated on the flanks of synsedimentary basement antiforms. Vertical growth of antiforms caused progressive tilting of beds, layerparallel extension by boudinage and faulting, and induced redeposition by mass flow. Antiforms are localised in the dextral Budaörs shear zone and in the Buda
imbricate stack, which accommodated the dextral displacement. The latter is underlain by blind reverse faults probably merging into a detachment tault at shallow
depths. These structures were formed by WNW-ESE
oriented compression and NNE-SSW directed tension. The morphological expression of the imbricate stack is the SE-facing Buda slope.
The Bakony unit, while "escaping" from the Alps, was bordered by a northern sinistral and a southern dextral
shear zone. Synsedimentary tectonics in the Buda Hills demonstrates the style of deformation inside the escaping block, close to the southern border zone. Tectonically controlled sedimentation suggests that escape tectonics was active as early as Late Eocene time

Embouchure injuries and issues in brass players: the importance of prevention and rehabilitation
No full textMagistrska naloga z naslovom Poškodbe in težave z nastavkom pri trobilcih: pomen preventive in rehabilitacije je teoretično raziskovalno delo, ki se po začetnem opisu anatomije nastavka poglobi v možne vzroke, zaradi katerih lahko funkcionalen nastavek trobilca postane disfunkcionalen ter posledično povzroči t. i. nastavkovno dilemo, poškodbe ali nevrološke težave, ki lahko resno ogrozijo glasbenikovo kariero in posledično tudi negativno vplivajo na njegovo duševno zdravje. V nadaljevanju so podrobno opisane doslej poznane metode rehabilitacije tako fizične kot psihične narave, ki morajo biti uporabljene sočasno, saj je najučinkovitejši pristop holističen in drugačen za vsakega posameznika. Na koncu naloge so izpostavljeni tudi preventivni ukrepi, preko katerih bi se lahko trobilec z rednim izvajanjem izognil omenjenim resnim težavam. Cilj naloge je bil raziskati ta vidik kariere trobilca, ki je trenutno dokaj neraziskano področje, pri čemer so tudi viri in rezultati raznih raziskav na to temo še vedno zelo razpršeni. Naloga tako pojasnjuje vzroke in posledice težav nastavka ter navaja metode rehabilitacije in preventive.The Master\u27s thesis titled Embouchure Injuries and Issues in Brass Players: The Importance of Prevention and Rehabilitation is a theoretical research work that, after an initial description of embouchure anatomy, delves into the possible causes that can transform a brass player\u27s functional embouchure into a dysfunctional one, consequently leading to what is known as »embouchure dilemma«, injuries, or neurological issues that can seriously jeopardize a musician’s career and, in turn, negatively affect their mental health. The following sections provide a detailed description of the currently known rehabilitation methods, both physical and psychological in nature, that must be applied simultaneously, as the most effective approach is holistic and individualized. At the end of the thesis, preventive measures are also highlighted, through which a brass player, with regular practice, could avoid these serious issues. The goal of this work was to explore this aspect of a brass player\u27s career, which is still a largely under-researched area, and to address the dispersed sources and results of various studies on the subject. This thesis thus clarifies the causes and consequences of embouchure issues and presents methods for rehabilitation and prevention
Sensory acceptance of reformulated ice cream
No full textNamen raziskave je bil določiti razlike v fizikalno-kemijskih in senzoričnih lastnostih standardnega vzorca v primerjavi z reformuliranim vzorcem sladoleda na palčki. Analizirali smo štiri pare vzorcev, ki smo jim določili hranilne vrednosti s fizikalno-kemijskimi analizami in iz podatkov izračunali vrednost Nutri-Score. S senzorično analizo smo s preskusom primerjave v parih preverjali, če obstajajo razlike v sladkosti med vzorcema v paru. Z opisno metodo »Označi vse kar ustreza« (CATA) smo določili opisnike, ki jih mladi potrošniki povezujejo z vzorci. Na koncu smo z ocenjevanjem na 9-točkovni lestvici določili stopnjo ugajanja posameznih senzoričnih lastnosti in celokupno všečnost vsakega vzorca. Pripravili smo tudi anketni vprašalnik o potrošniških navadah, povezanih z uživanjem sladoleda. Reformulirani vzorci so imeli manjšo vsebnost ogljikovih hidratov, sladkorjev in posledično nižjo energijsko vrednost. Vsebovali so več prehranskih vlaknin in beljakovin. Vsebnost maščob se je statistično razlikovala le pri dveh parih, kjer je imel reformuliran vzorec nižjo vrednost. Prav tako so reformulirani vzorci prejeli Nutri-Score oceno C, medtem ko so standardni vzorci prejeli za en razred slabšo oceno D. Pri treh parih smo dokazali razliko v intenzivnosti sladkega okusa. V ocenjevanju z metodo CATA se je večina opisnikov v paru skladala in prav tako pri hedonskem ocenjevanju znotraj parov ni bilo značilnih razlik med povprečnimi hedonskimi ocenami. Rezultati anketnega vprašalnika so pokazali, da študentje uživajo sladoled najpogosteje poleti, nekajkrat na teden s prijatelji ali kot posladek. Večina ni pozornih na hranilno vrednost sladoleda, najljubši so jim tradicionalni okusi in raje imajo mlečni sladoled v kornetu, ki ga pogosteje kupijo v trgovinah.The aim of this research was to determine the differences in the physical-chemical and sensory properties of the standard sample compared to the reformulated samples of ice cream on a stick. We analyzed four pairs of samples, for which we determined the nutritional values by physical-chemical analysis and calculated the Nutri-Score value from the data. Sensory analysis was used to determine differences in sweetness within pairs using a paired comparison discrimination test. Using the descriptive \u27Check all that apply\u27 (CATA) method, we determined the descriptors that young consumers associate with the samples. With a 9-point scale, we rated their attribute liking of and the overall liking. We also prepared a questionnaire on consumer habits related to the consumption of ice cream. The reformulated samples had a low content of carbohydrates, sugars and consequently a lower energy value. They had a higher value of dietary fiber and protein. The fat content was statistically different only in two pairs, where the reformulated sample had a lower value. The reformulated samples received a Nutri-Score score of C, while the standard samples received one grade worse score of D. In three pairs, we determined a difference in the intensity of sweetness. In the evaluation with CATA, most of the descriptors in the pair were similar, and in the hedonic evaluation, there were no significant differences in liking within the pairs. In the questionnaire, we determined that students consume ice cream most often in the summer, several times a week with friends or as a dessert. Most of them do not pay attention to the nutritional value of ice cream, they prefer traditional flavors, milk ice cream in a cone, which is more often bought in stores
Sensory properties of spices and the possibility of use in bakery products
No full textV živilski industriji se začimbe uporablja kot dodatek različnim živilom za izboljšanje senzoričnih lastnosti (barve, vonja, okusa in arome) ter kot antioksidante in protimikrobna sredstva. Kot začimbe uporabljamo različne dele rastlin, liste, semena, lubje, plodove in korenine. Pri ocenjevanju senzoričnih lastnosti različnih začimb si lahko pomagamo z McCormickovim senzoričnim kolesom začimb, ki vključuje senzorične opisnike za vonj in aromo. Proučili smo možnosti uporabe začimb v pekovskih izdelkih kot dodatkov za izboljšanje barve in arome ter kot antioksidativnih in protimikrobnih učinkovin. V okviru eksperimentalnega dela diplomskega dela smo želeli raziskati vpliv dodatka izbranih začimb (janeža, pimenta, ingverja in kurkume) na všečnost nekaterih senzoričnih lastnosti (videz, vonj, okus, aroma, krhkost, topnost) in celokupno všečnost piškotov. Spekli smo piškote z dodatkom začimb in jih senzorično ocenili s panelom študentov. Večje razlike med vzorci so bile pri videzu, vonju, okusu in aromi. Kontrolni vzorec brez začimb je prejel najvišje ocene pri večini senzoričnih lastnosti, razen videzu, kjer so bili bolje ocenjeni le piškoti z ingverjem. Pri ocenjevanju topnosti in krhkosti piškotov so bili rezultati med vzorci primerljivi. Pri ocenjevanju celokupne všečnosti so študenti najboljše ocenili kontrolne piškote brez dodatkov, sledili so piškoti z janežem, nato piškoti z dodatkom pimenta, najslabše so bili ocenjeni piškoti z ingverjem in s kurkumo. Pri dodatku ingverja je študente najbolj zmotil pekoč pookus piškotov, pri dodatku kurkume pa preveč intenzivna rumena barva.In food industry, spices are mostly used to improve colour, odour, taste and aroma of different foods, and as antioxidants and antimicrobial agents. Spices come from different parts of plants, such as leaves, seeds, bark, fruits, roots, berries and pods. Sensory properties of different spices can be described with McCormick\u27s spice wheel, which includes sensory descriptors for odour and aroma. In graduation thesis we have studied the use of spices in bakery products for improvement of colour and aroma, and antioxidant and antimicrobial activity. Also we wanted to investigate the effect of the addition of selected spices (anise, allspice, ginger and turmeric) on some sensory properties (appearance, odour, taste, aroma, fragility and solubility) and overall liking of cookies. The cookies were prepared with addition of spices and then sensory evaluated with a panel of students. The major differences between the cookies were in appearance, odour, taste and aroma. The control sample (without spices) received the highest scores for most sensory properties except for the appearance, where only cookies with ginger were evaluated better. In assessing the solubility and fragility of cookies the hedonic scores were comparable between the samples. In evaluating the overall likeness, the best results were obtained for the control, followed by cookies with anise and allspice, while the lowest scores were obtained for cookies with ginger and turmeric. Cookies with ginger received lower hedonic score because of spicy, burning aftertaste, whereas cookies with turmeric were evaluated lower because of too intense yellow colour
Investigating stakeholders’ opinion on energy retrofit of historic buildings, grasping their needs and experiences. An overview on the use of retrofit guidelines and decisional tools
No full textThis paper aims to explore what information do refurbishment stakeholders find useful to support the decision-making and what are the key points during the retrofit design process to consider. Decisions concerning
the improvement of conditions and performance of historic buildings are not only about solving technical
problems: decisions revolved around balancing different objectives and value judgments. Hence, what guides different stakeholders in constructing their opinions? How are they influenced? What matters more in the process? For this purpose, in this article different stakeholders have been interviewed to understand how to
activate a negotiation process that functions in real-life interactions, with the support of experts in social science.
The observations of many heritage officers, architects and energy professionals were gathered to better understand how energy retrofit guidelines, the EN 16883:2017 and the Italian retrofit guidelines for historic buildings by the Cultural Heritage Ministry (MiBACT), are used in practice
Osteoarticular grafts in the treatment of OCD of the talus: mosaicplasty versus autologous chondrocyte transplantation
No full textFurther advancements in articular cartilage transplantation require an understanding of the anatomy, physiology, biomaterials, biology, and cartilage engineering that are fundamental for better results in joint arthroplasty and cartilage repair. Currently, efforts to induce healing and regeneration of cartilage are being directed toward enhancing the natural potential of cartilage to replace the damaged tissue with cells that can generate cartilage. Mosaicplasty and ACT are carried out in the same way, have similar therapeutic indications, and have been demonstrated capable of reconstructing hyaline cartilage with similar clinical results. ACT is the most recent technique and, in the authors' opinion, is preferable in that it is less invasive at the donor site and gives better histologic results because of the reconstruction of a continuous cartilage sheath compared with that achieved by mosaicplasty. Furthermore, with this technique, it is possible to forecast the possibility of improvement owing to further technical and biologic advancements. The authors are currently experimenting with the use of adhesive patches with substitution of the periosteum, resulting in less morbidity. The use of growth factors and new tissue engineering techniques in the future would simplify the methodology, rendering it less invasive and more effective
Blip-Up Blip-Down Circular EPI (BUDA-cEPI) for Distortion-Free dMRI with Rapid Unrolled Deep Learning Reconstruction
No full textPurpose: We implemented the blip-up, blip-down circular echo planar imaging
(BUDA-cEPI) sequence with readout and phase partial Fourier to reduced
off-resonance effect and T2* blurring. BUDA-cEPI reconstruction with S-based
low-rank modeling of local k-space neighborhoods (S-LORAKS) is shown to be
effective at reconstructing the highly under-sampled BUDA-cEPI data, but it is
computationally intensive. Thus, we developed an ML-based reconstruction
technique termed "BUDA-cEPI RUN-UP" to enable fast reconstruction.
Methods: BUDA-cEPI RUN-UP - a model-based framework that incorporates
off-resonance and eddy current effects was unrolled through an artificial
neural network with only six gradient updates. The unrolled network alternates
between data consistency (i.e., forward BUDA-cEPI and its adjoint) and
regularization steps where U-Net plays a role as the regularizer. To handle the
partial Fourier effect, the virtual coil concept was also incorporated into the
reconstruction to effectively take advantage of the smooth phase prior, and
trained to predict the ground-truth images obtained by BUDA-cEPI with S-LORAKS.
Results: BUDA-cEPI with S-LORAKS reconstruction enabled the management of
off-resonance, partial Fourier, and residual aliasing artifacts. However, the
reconstruction time is approximately 225 seconds per slice, which may not be
practical in a clinical setting. In contrast, the proposed BUDA-cEPI RUN-UP
yielded similar results to BUDA-cEPI with S-LORAKS, with less than a 5%
normalized root mean square error detected, while the reconstruction time is
approximately 3 seconds.
Conclusion: BUDA-cEPI RUN-UP was shown to reduce the reconstruction time by
~88x when compared to the state-of-the-art technique, while preserving imaging
details as demonstrated through DTI application.Comment: Number: Figures: 8 Tables: 3 References: 7
Natureza, Ética(s) e Dharma do Buda
No full textComo resultado de incompreensão da complexidade e abrangência dos sistemas de vida (nesciência eco-sistémica) vivemos hoje em um mundo global que acolhe e implementa os valores de um hedonismo materialista, expressos em modos de vida consumistas onde imperam a dualidade, a competição, o extrativismo e produtivismo, assim como o stress, burnout e depressão. Sofremos os resultados da implementação de um monismo materialista (dito) científico associado a um dualismo cartesiano que, em conjunto, decidem a vida de milhares de milhões de humanos assim como de toda a Ecosfera. Este materialismo - quando plasmado em conhecimento científico e saber prático tecnológico - tem cooperado também para um quadro mais alargado de problemas. Como poderemos implementar compromissos sérios pela não-violência e altruísmo abrangente, amor pela natureza e gosto pela inquirição aberta e franca ao invés de distração crónica? Na verdade, são os olhares profundos e inclusivos que permitem filosofias de vida verdadeiramente humanas (ecosofias). Instituir uma harmonia ecológica, ou seja, uma verdadeira epistéme das interações que tende a manter ciclos e equilíbrios, porque não-dual mas sim ecocentrada, eis o que mais importa. Este texto, partindo destas preocupações, de modo sintético, levanta questões, propõe reflexões e aponta para soluções éticas extraídas de um olhar sobre o Dharma do Buda (Budismo).
